I went to have it smog tested and it ran high hydro carbons at idle idle was 690-710 and it passed everything else/ My question is this the problem or can I test this first. I am not a part changer but a problem solver..Any input would be appreciated. Thank you. Bruce williams P.s. its an 89 5.0 non h.o. crown vicky IP: Logged

Looks like you have a bad EGR valve position sensor. ------------------ '70 Mustang Mach 1 351C 4V/FMX/3.25 Open '70 Mustang Convertible 250 I6/3 speed/2.79 Open '72 Mustang Sprint Hardtop 351C 4V/FMX/4.30 Trac Loc '94 F-150 XL 5.8L/E4OD/3.55 Limited Slip IP: Logged

The tech probably checked your EGR {I guess I shouldn't assume anything these days} valve by either a vacuum test or by manipulating the rod underneath the diaphram if possible. If you want to take a shot at something, you could take the EGR off and clean the plunger with carb cleaner. Hopefully the gasket will survive the R&R. ------------------ '70 Mustang Mach 1 351C 4V/FMX/3.25 Open '70 Mustang Convertible 250 I6/3 speed/2.79 Open '72 Mustang Sprint Hardtop 351C 4V/FMX/4.30 Trac Loc '94 F-150 XL 5.8L/E4OD/3.55 Limited Slip IP: Logged
